WATCH-OILER.

SPECIFICATION forming part of Letters Patent No. 487,732, dated December 13, 1892.

Application led April 5, 1892. Serial No. 427,893. (No model.)

To (fr/ZZ whom it may concern.:

Be it known that I, IRA L. GREEN, a citizen of the United States, residing at St. Regis Falls, in the county of Franklin and State of New York, have invented a new and useful Watch-Oiler, of which the following is a specification.

My invention relates to improvements in Oilers to be used in lubricating the wearing parts in the movements of watches and other delicate mechanisms.

The objects in view are to provide an oiler that may be readily filled, which will preserve the oil from its accidental escape or from contact with dust, and which is so constructed as to especially adapt it to deposit small particles of oil into the oil-cups of the jewels and other places of friction.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of an oiler embodying my invention. Fig. 2 is an exaggerated longitudinal sectional view. Fig. 3 is an enlarged detail in perspective of the oil-distributing point.

Fig. .it is a detail of the glass reservoir. Fig. 5 is a similar view of the tube for receiving the reservoir. Fig. 6 is a separated View of the three elements composing the reservoiroperating device. Fig. 7 is a detail in perspective of the corrugated air admitting washer. Fig. S is a transverse section through the tube shown in Fig. 5, said section being taken through the spring-tongues.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing myinvention I employ a preferably-cylindrical outer metal tube or casing 1, the upper end of which is inwardly turned to `form an annular shallow flange 2, which at one side l provide with a notch or recess v 3. Located within this tube is a washer et,

and the same is uted or corrugated, forming a series of air spaces or passages 5.

In the lower end of the tube or casing 1 is fitted a removable cap 6, and the same comprises, in addition to a central teat 7, a surrounding polygonal tlange 8 and an annular flange or collar 9, the latter fitting snugly,

though removably, into the lower end of the tube. The flange 9 may be threaded exteriorly, if desired, and in this manner secured in position in the tube, though such is not necessary, and I prefer that the flange be plain, in order that the parts may be readily separated for cleaning, die. Vthen the device is at rest or lying upon a bench, the polygonal flange prevents the same from rolling from the bench, and, extending slightly beyond the exterior surface of the cylinder casing or tube 1, forms a support and maintains the discharge-point, hereinafter described, out of contact with the bench and the minute particles of foreign matter thereon.

To the teatof the lower cap above described and extending through the same is the discharge-point 10, and this Apoint is preferably formed of gold and hammered out to give the sameaiine temper. The lowerend ofthe point is slit, forming opposite terminals 11, and the intermediate discharge 12 and the terminals are flattened, as before mentioned, to improve their temper and give the requisite thickness. The upper end of the discharge-point is wit-hin the cap and forms a seat 13.

14 designates a finely-coiled spring, fitting somewhat snugly within the cylindrical tube or casing 1 and having its lower end bearing on the lower cap, just above described. A thin metal tube 15 fits somewhat snugly within the spring, and near its lower end is provided at intervals with narrow slits 16, forming intermediate spring detents or portions 17, which are very slightly converged. Into this metal tube, which I will term a reservoir-tube, there is inserted a glass reservoir 18. This glass reservoir may be slid into and out of the reservoir-tube and will be held in any of its positions by means of frictional contact with the aforesaid spring detents or portions 17. The lower end of the reservoir is drawn out to form a point 19, which is directly above or in line with and a short distance from the seat at the upper end of the discharge-point.

In the upper end of the tube or casing 1 a plunger is fitted, and the same consists of a tubular body portion 20, provided at its lower end with an enlarged boss or head 21 and above the same with a slot 22. A cap 23 fits over the upper end of the tubular body portion, and has a perforation 24, threaded and regis-- ICO tering with the aforesaid slot. A screw 2rpasses through the perforation of the cap and slot of the plunger and serves to connect the two against longitudinal separation. The head of the screw projects from the cap and forms a lug, as it were, the purpose of which will be hereinafter explained. The upper end of the cap is provided with a milled head 26, and between the lower end of the cap and the boss at the lower end of the plunger, a light coiled spring 2S encircles the body portion of the plunger. The lower end of the plunger takes within the upper end of the reservoirtube, and the head of the sciew of the plunger projecting from the latter, in addition to serving its function as a screw, also serves to engage with the flange 2 of the casing l, thus interlocking with the iiange. It will be seen that by a slight rotation of the plungernamely, until the head of the screw arrives opposite the notch or recess in the upper end of the casing 1 or its flange 2-the said plunger maybe removed from its interlocking p0- sition.

In operation in order to fill the reservoir with oil the plunger is disconnected and withdrawn from the tube l and with it is removed the reservoir and its tube. Now by pressing the plunger the reservoir is extended or longitudinally slid from its tube and its lower end is immersed into the bottle of oil, which oil rises in the reservoir, filling the same. It now requires but the work of an instant to return the parts to their foi-nier position, and in order to place the oiler in condition for operation the plunger is now pressed by the forefinger of the operator until the lower end of the glass reservoir is in contact with the seat at the upper end of the discharge-point. Such connection being made, the oil will run from the reservoir to the discharge'point, the connection being maintained until the point is filled or enough has flowed from the reservoir into the point to meet the requirements of the occasion. The plunger is now released. The connection between the reservoir and point being broken or destroyed, the fiow of oil is arrested and the discharge-point is ready to be applied to the jewels or other wearing portions of watches and Various ne machinery.

From the foregoing description, in connection with the accompanying drawings, it will be seen that I have provided an oiler which is not complicated iu construction and is practically dust-proof, thus preserving the oil against contact with the same and preventing in this manner the introduction of foreign bodies into the movements of watches, that the oiler may be readilyseparated and cleaned and its supply may be regulated by the operator in accordance with the demand. By reason of the fiuted or corrugated washer Il air is admitted between it and the tubular casing and through minute perforations 29, with which the reservoir-tube is provided iinmediately above the upper end of the glass reservoir.
